what a "progressive" (and i'm just co-opting the term, here, with a dictionary definition) politics should be based around is helping people out of these cults - which means providing them with support to break free from them. that holds for sikhism, islam, christianity, judaism and all the rest.
the last thing that a "progressive" politics should be doing is giving these religious groups a platform, or helping to put them into power.
electing a guy with a turban would be a step backwards, and let's hope we're never "ready" for it.
